I enjoyed your article, especially the Tolstoy bit.
It strikes me though that there is a significant difference between the Russian Orthodoxy embraced by Tolstoy and Solzhenitsyn and contemporary American Evangelicalism.
Orthodoxy provides an unbroken tradition back to the early Church. Protestantism is steeped in rebellion against the short comings of Roman Catholicism.
Much of the millenial reaction I am seeing to the Church in America is a response to what they perceive as a rejection of the heart of the Gospel by church leaders.
The ease with which many church leaders have embraced the entire Republican platform and the agenda of Donald Trump has convinced many that the church wants power more than living lives of self sacrificial love.
Certainly the Russian Orthodox Church fell into the same trap. I don't want to speak for millenials as I am Gen X, but I think a lot of them would like to see evidence of the Church repenting of complicity with imperialism, supporting policies which aid the wealthy more than the poor, and ways in which preserving white supremacy have seemed more important than embracing everyone as a precious child of God.
